1) The document summarizes the results of running all tutorials in OpenFOAM-v1612+. 2) When compared to v1606+, the number of cases increased significantly (by 28) but there were no changes in abnormal termination cases. Calculation speed varied greatly between cases (over 20% change for 21 cases). 3) When compared to v4.1, the number of cases increased greatly (by 47) and the number of abnormal termination cases decreased. Calculation speed varied significantly between cases (over 20% change for 24 cases) with some SNAPPYHEXMESH cases showing a slight increase in calculation time (similar to v3.0+ vs 3.0.1).
